Rate Limits

Per-key limits are applied based on your plan.

Quotas reset at midnight UTC. If you exceed a limit you’ll see 429 Too Many Requests with Retry-After.

Handling 429

Code
 
async function fetchWithBackoff(url: string, opts: RequestInit, attempt = 0) {
  const res = await fetch(url, opts);
  if (res.status !== 429) return res;
  const retryAfter = parseInt(res.headers.get('Retry-After') || '0', 10);
  const backoff = Math.min(30000, Math.pow(2, attempt) * 500);
  await new Promise(r => setTimeout(r, Math.max(retryAfter * 1000, backoff)));
  return fetchWithBackoff(url, opts, attempt + 1);
}
